摘要： An object of the present invention is to provide an ink jet print head configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. To achieve the object, an individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber 40 are made symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of a pressure chamber 40.
